# Round Timer vs Interval Timer ++

The clearest difference is ratings volume: Interval Timer ++ at 15K against Round Timer's 296. Interval Timer ++ also leads on iOS requirement (12.0 vs 15.0). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Round Timer sells 8 in-app purchases, starting at $3.99 per month and Interval Timer ++ sells 8 in-app purchases, starting at $0.99 per 2 months. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Round Timer against 4.8 for Interval Timer ++. That said, the two scores are not equally well evidenced: Interval Timer ++ has 15K ratings behind it against 296, so its average is the more settled of the two. Written reviews are what separate them: 73% of Round Timer's written reviews are positive against 78% of Interval Timer ++'s.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 12, 2026 and September 25, 2026 respectively.
